20 Claims. (Cl. 297-85) This invention relates to reclining chairs of the type which include a separate back-rest, a separate seat and a separate leg-rest that are movable with respect to each other in response to pressure applied to the back-rest, for placing said body-supporting parts of the chair in a multiplicity of relative positions.

An object of the present invention is to provide a chair of the indicated type with improved means for actuating the various body-supporting parts of the chair to place illustrative of an embodiment of the invention and not in limitation thereof.

In the drawings:

FIG. 1 is a side elevational view of a reclining chair in accordance with the present invention, illustrating the body-supporting parts of the chair in an upright or sitting position; i

FIG. 2 is a side elevational view of the chair of FIG. 1, illustrating the body-supporting parts of the chair in a reclined position, such as mightbe suitable for television viewing;

FIG. 3 is a side elevational view of the chair of FIG. 1, illustrating the body-supporting parts of the chair in a lounging position;

FIG. 4 is a side elevational view of the chair of FIG. 1, illustrating the body-supporting parts of the chair in a sleeping position;

FIG. 5 is a top plan view, with parts broken away, of the operating linkage mechanism of the chair, showing the parts thereof in an expanded condition for purposes of illustration;

FIG. 6 is a side elevational view of part of the linkage mechanism of the chair, illustrating a modification thereof; and r FIG. 7 is a side elevational view of part of the linkage mechanism of the chair, and illustrates another modification thereof.

Referring now to the drawings in detail, the reclining chair 10 comprises a frame 12 supported on legs 14. A support plate 16 is suitably secured to each side of frame 12 and supports the parts of the operating linkage mechanism of the chair, which is provided at each side of the chair, as will be more clearly understood hereinafter. The body-supporting means of the chair includes a separate and movable back-rest 18, a separate and movable seat 20 which can be provided with a cushion 22, and a separate and movable leg-rest 24.

The back-rest 18, seat 22, and leg-rest 24 are operatively connected to each other through an operating linkage mechanism, generally designated by the reference numeral 26, so that in response to pressure on the back-rest 18 as,

for example, by a person pushing his back against the back-rest to actuate the linkage mechanism, the bodysupporting parts of the chair move into the successive positions illustrated by FIGS. 1 to 4, respectively. FIG. 1 illustrates the upright position of the chair; FIG. 2 illustrates the partial reclining or TV viewing position of the chair; FIG. 3 illustrates the full reclining or lounging position of the chair and FIG. 4 illustrates the sleeping position of the chair. The body-supporting parts of the chair are moved back to the upright position of the chair, illustrated by FIG. 1, from the sleeping position of the chair, illustrated by FIG. 4, by the application of pressure on seat 20, as, for example, by the sitter applying pressure against the seat through his buttocks.

Back-rest 18 is fixedly connected to a link 28 which has its rearward end pivotally connected at 30 to the upper end of a link 32 that is connected at its lower end to a pivot 34 which is fixedly connected to plate 16. Seat 20 is fixedly connected to a link 36 which is pivotally connected at its rearward end, at 38, to the forward end of link 28, and is pivotally connected at its forward end, at 40, at the upper end of a link 42. Near pivot 38, the upper end of a link 44 is pivotally connected at 46 to link 36 and the lower end of link 44 is pivotally connected at 48 to the forward end of a bell-crank 59 which is pivotally connected at 52 to plate 16. Near the forward pivot end 40 of link 36, the upper end of a link 54 is pivotally connected at 56 to link 36 and intermediate its length, link 54 is pivotally connected at 58 to the forward end of another bell-crank 60 which is pivotally connected at 62 to plate 16. The lower end of link 54 is pivotally connected at 64 to the rearward end of a link 66 whose forward end is pivotally connected at 68 to link 42, at a position intermediate its length.

Links 54 and 66 operate leg-rest 24 in response to movement of link 36. More particularly, the upper end of a link 70 is pivotally connected at 72 to link 36 at a position between pivots 40 and 56. The lower end of link 70 is pivotally connected at 74 to the lower end of a link 76 and the upper end of the latter is pivotally connected at 78 to the upper end of a support 79 on which leg-rest 24 is mounted. Links 42 and 76 are pivotally interconnected at 80 at a position near the lower ends of the links. The lower end of link 42 is pivotally connected at 82 to the lower end of a link 84 which is pivotally connected at its upper end, at 86, to leg-rest support 79, at a position above the lower end thereof.

It is to be observed from the above described operating interconnection of the back-rest 18, seat 20 and leg-rest 24, that pressure applied against the back-rest causes the latter to rotate rearwardly and downwardly on link 32 about fixed pivot 34, while seat 20, which is connected to link 36, rotates rearwardly on links 54 and 44, about pivots 58 and 48, respectively. At the same time, footrest 24 moves forwardly and upwardly about pivots 72 and 40 in response to forward movement of links 54 and 66. The foregoing movements continue until stud 88, which is secured to links 36 and extends from the side thereof, engages the forward edge of link 44, as shown in FIG. 2, at which time the body-supporting parts 18, 20 and 24 of the chair are in a reclining position which is especially suitable for television viewing. Links 28, 32 and 36 comprise first operating linkage means or the operating means for the back-rest and seat for movement thereof from the first position to the second position of the chair.

Additional pressure on back-rest 18 causes bell-cranks 60 and St) to rotate in a clockwise direction, as viewed in FIG. 2, about their fixed pivots 62 and 52, respectively,

thereby raising seat 20 and moving back rest 18 in a rearward and downward direction into the positions shown in FIG. 3, which is the lounging position of the chair. For releasably holding the different parts of the chair in their lounging positions, a link 90 is provided which is pivotally connected at its rearward end, at 92, to the rear lower end of bell-crank 50, and the forward end of the link is pivotally connected at 94 to the rearward end of bell-crank 69. A lever 96 is pivotally connected at its forward end to-a fixed pivot 98 which is mounted on plate 16. The rearward end of lever )6 carries a stud 100 which is biased, by a torsionspring 102, into sliding engagement with the upper edge of link 90 which is provided with a wedge-shaped slot 104. The movements of the parts of the chair continue from their respective positions shown in FIG. 2 until stud 100 moves into slot 104, at which time the chair is in its lounging position as illustrated by FIG. 3.

Further pressure on back-rest 18 causes stud 100 to be cammed out of slot 104, thereby permitting further rotation of bell-cranks 60 and 56. Rotation of the bellcranks continues until the lower edge of bell-crank 60 engages stop-stud 106 which extends from the side of plate '16, at which time the parts of the chair are in their sleeping position as shown in FIG. 4.

The parts of the chair are returned to their upright position by the user sitting up in the chair whereby the pressure against seat 20 automatically causes reverse movement of the parts into the positions illustrated by FIG. 1. A stop-stud 108 is provided and extends from the side of plate 16 in the path of movement of the lower edge of bell-crank 60 for engaging the latter in the 'upright position of the chair and thereby prevents further movement of the parts of the chair after they are in their proper positions corresponding to said upright position, as illustrated by 'FIG. 1.

Means is provided to prevent rotation of bell-cranks 60 and 50 which, with links 44, 54 and 90 comprise second operating linkage means of the actuating means of the back-rest and seat for movement thereof into said third and fourth positions, during the movements of the parts of the linkage operating mechanism 26 as the chair is moved through a first phase of movement from an upright position, illustrated by FIG. 1, to a partially reclining or TV viewing position, illustrated by FIG. 2. To this end there is provided a sequencing mechanism 110. The sequencing mechanism 110 comprises a sequence member 112, which is in the form of a plate that has an upper stop edge 114. Member 112 is pivotally mounted at its lower forward corner, at 116, to the forward end of crank 50. A roller 118 extends from the side of the sequence member, at its rear upper corner, and is biased by a torsion spring 120 in a direction which causes stop edge 114 (FIG. 1) to engage a stop-stud or keeper 122 that extends from the side of plate 16.

During the rearward movement of link 44 about its pivot 48, while the linkage mechanism 26 is being actuated from the upright position of the chair to the reclining position of the chair, as illustrated by FIGS. 1 and 2, respectively, the rearward edge of link 44 engages roller 118 and thereby causes member 112 to rotate clockwise, as viewed in FIG. 1, about its pivot 116. However, stop edge 114 still remains in engagement with stop-stud 122, thereby preventing rotation of the bell-cranks. As the linkage mechanism moves into its position corresponding to the reclining position of the chair, member 112 has rotated a sufiicient amount, as illustrated by FIG. '2, so that edge 114 is no longer in engagement with stop-stud 122, and the bell-cranks are free to rotate upon the application of further pressure against back-rest 18 for moving the chair into its lounging position.

As illustrated by FIG. 6, other means can be provided for locating the lounging position of the chair in lieu of the spring-biased lever 96 and slot 104 in link 90, and which also eliminates stop-stud 106 for the sleeping position of the chair. More particularly a slotted link 124 is provided which is slidably mounted on studs 126 and 128 that extend from the side of plate 16 through slot 130 of the link. A helical tension spring 132 has its rearward end fixed to a pin 134 which extends from the side of plate 16 and the forward end of the spring is fixed to a pin 136 which extends from the side of link 124, at the rear end thereof. The spring normally biases the link into the position shown in FIG. 6, with stud 126'in engagement with the forward end of the slot.

As link 60', which is the same as link 60 but which has been modified to provide a link engaging edge 138, moves from its position corresponding to the reclining position of the chair, illustrated in solid'lines in FIG. 6, to its position corresponding to the lounging position of the chair, illustrated by dashed lines in FIG. 6, edge 138 of link '60'engages the rearward end of link 124 to stop the movement of the operating linkage mechanism 26 as it moves into position corresponding to the lounging position of the chair. Additional pressure on back-rest 18 to move the chair into its sleeping position, causes sliding movement of link 124, due to the forward movement of link 60', until the rearward end of slot 130 engages stud 128 to stop further movement of the parts of the chair after they are in the sleeping position of the chair. It is to be noted that spring 132 provides a counter-balancing force as the chair is moved from its lounging position to its sleeping position and this counter-balancing force assists 'inthe return of the chair from its sleeping position to its lounging position.

If desired or required, it is within the scope of this invention to eliminate the fourth or sleeping position of the chair. This may be accomplished, as illustrated by FIG. 7, by eliminating lever 96, spring 102 and slot 104 in link 90, and the modification illustrated by FIG. 6, and moving stop-stud 106 rearwardly, so that crank 60 engages said stop-stud when the crank is in its position corresponding to the lounging position of the chair.

As is apparent, to return the chair from the fourth or sleeping position or from the third or lounging position illustrated by FIGS. 3 and 4, respectively, to its upright position illustrated by FIG. 1, it is not necessary to go back through the other positions. The chair may be returned directly to its upright position by applying pressure directly to leg-rest 24 to collapse the leg-rest operating linkage mechanism into the position illustrated by FIG. 1, wherein sequence member 112 is positioned above stop-stud 122 with its cam edge 114a also above the stud. Downward and direct return movement of the chair seat into the position illustrated by FIG. 1 causes stud 122 to engage cam edge 114a and rotate sequence member 112 clockwise as viewed in FIG. 1, permitting cam edge 114 to move under stud 122 and snap back into its normally locked position illustrated by FIG. 1.

While I have shown and described the preferred embodiment of the invention, it will be understood that the invention may be embodied otherwise than as herein specifically illustrated or described, and that certain changes in the form and arrangement of parts and in the specific manner of practicing the invention may be made without departing from the underlying ideas or principle of the invention within the scope of the appended claims.
